The Clinton campaign is still looking for someone to play Donald
Trump in preparation for the presidential debates in September
and October.

In a Sunday interview on CNN's "State of the
Union," Clinton's campaign manager, Robby
Mook, said they haven't settled on an opponent to play
the outspoken Republican presidential nominee because he's
difficult to mimic.

"It's very hard to find someone to mimic the reckless temperament
and the hateful instincts and divisive instincts of Donald Trump.
Preparing for a debate with him is a challenging task," Mook
said.

Mook denied that the campaign was having difficulty finding
someone willing to criticize the Democratic presidential
nominee and raise sensitive potential lines of attack.

"She has been in this game a long time. She has had a lot of
tough things said to her. That's not the challenge here," Mook
said.

The Clinton campaign is keeping its debate prep under wraps. But
Politico recently reported that the campaign is
readying the former secretary of state to face questions
with a personal and conspiratorial bent.

Some observers have speculated that potential picks to play Trump
include Sen. Al Franken, a former "Saturday Night Live" cast
member and comedian, and former Pennsylvania Gov. Ed
Rendell, who
joked recently that his proclivity for Trump-like
outspokenness could make him a good debate sparring partner.

For its part, the Trump campaign appears to be preparing for the
debate already. The real-estate magnate reportedly
sought advice from former Fox News CEO Roger Ailes in his
debate-prep sessions, though the campaign has denied Ailes'
involvement.
